The confidence intervals for [mi=0] and [mi=1] do not overlap with the interval for [mi=2], and none of them include 0. Therefore, it appears that the hazard for patients with one or no prior mi’s is distinguishable from the hazard for patients with two prior mi’s, which in turn is distinguishable from the hazard for patients with three prior mi’s.
Similar relationships hold for the levels of is and hs, where increasing the number of prior incidents increases the hazard of death.

Pattern values
The pattern values table lists the values that define each predictor pattern. In addition to the predictors in the model, the start and end times for the survival interval are displayed. For analyses run from the dialogs, the start and end times will always be 0 and unbounded, respectively; through syntax you can specify piecewise constant predictor paths.
The reference pattern is set at the reference category for each factor and the mean value of each covariate (there are no covariates in this model). For this dataset, the combination of factors shown for the reference model cannot occur, so we will ignore the
Patterns 1.1 through 1.4 differ only on the value of History of myocardial infarction. A separate pattern (and separate line in the requested plot) is created for each value of History of myocardial infarction while the other variables are held constant.
